HP StorageWorks ESL9000 Tape Library - Manual (Page 30)

Library Description
30 HP StorageWorks ESL9000 Series Tape Library User Guide
The gripper includes a Class II laser bar code scanner that reads up to
12-character, 3-of-9 format bar code labels. The scanner is used to maintain an
inventory of the tape cartridges within the library. An inventory occurs
automatically each time the library is turned on, or after the bulk load door has
been closed. An inventory can also be initiated from the host computer.
Note: Although the library does not require tape cartridges to have bar code labels,
properly labeled tape cartridges and full storage bins speed up the inventory process.
Tape Drives
The following sections describe the tape drive technologies supported by the
library, including Ultrium and SDLT.
Caution: It is critical to ensure that the media you use matches the format of
your tape drive. Cleaning cartridges and formatted data cartridges are unique
for each drive technology. Damage may occur if inappropriate media is used
in tape drives.
Note: If using mixed media, ensure your software application supports it.
